SubjectPROBLEM: memory allocation error with token ring tms380/abyss modules
[1.] memory allocation error with token ring tms380/abyss modules

[2.] a memory allocation error causes the system to go into an infinite
loop about once every week or two. This most recent time was 8 days, to
the hour from the last crash. Everything on the system stops working and I
need to hit the reset button to reboot the system. At crash time, the
following message scrolls up the screen:

__alloc_pages: 1-order allocation failed

* Actually, I did some searching on the web and found this problem
discussed but not fixed. According to one e-mail, I patched
mm/page_alloc.c and rebuilt the kernel so that I could get the following
_slightly_ more informative message after the crash:

__alloc_pages: 1-order allocation failed from c01290e8

The modification I made to mm/page_alloc.c is:
change the line:

printk(KERN_ERR "__alloc_pages: %lu-order allocation failed.\n", order);

to:

printk(KERN_ERR "__alloc_pages: %lu-order allocation failed from %p\n",
order, __builtin_return_address(0));

Then I'm supposed to be able to look up the hex code from the error
message in the /boot/System.map (it is the correct one for my kernel) and
find out what function is causing the problem.

But, I don't find c01290e8 in my System.map. Two hex addresses close to it
are found there:

c01290d4 T __get_free_pages
c01290f4 T get_zeroed_page

Yup, looks like it has something to do with memory allocation alright ;-)

Everytime this crash occurs, it is the same hex address given in the error
message. I can't cause this error to occur. The system is running as a
basic router and has two Netgear FA310TX ethernet cards in it and one
Madge Smart 16/4 PCI Ringnode Mk2 token ring card in it.

The system logs don't give any indication that the crash is coming or any
information about it, not even the 1-order allocation error is listed.
One exception (maybe):

I get the following messages showing up occasionally in /var/log/messages
on weekdays (when I expect network usage to be higher than on weekends).
But these don't seem to come in any higher frequency leading up to the
crash.

[7.7] Its pretty standard PC hardware with the exception of the token ring
card which I know aren't nearly as widely used as ethernet cards.

Please help! =)

We're only using this "router" in testing at this point but would like to
roll it into our department's network. I won't do that as long as it is
crashing once a week.

If you need more information, I'll be happy to provide it let me know if I
can help.

Thanks,
Brian
